Review on 📶 Hollyland Mars 400S Pro [Official Dealer] | 1080p HDMI&SDI Transmission System | 5G Wireless Video & Audio Transmission | 400ft Range | 0.06s Latency | Live Stream Direct Video | Transmitter+Receiver | With Battery by William Hilzer

Impressive Range! I used this to broadcast a welding competition where the receiver was outside and the transmitter was on my camera walking through an almost all metal room. I assumed this would limit my range to under 400ft but I was very surprised that it held up great and even slightly over 400ft however there were some subtle injuries behind it. Very impressive! Battery life was decent too. I got at least 1.5 hours on one battery but I replaced them before they ran out so they last longer. I am using this with a Panasonic GH5 camera in a Black Magic ATEM Mini Switch. Picture quality is great too
